The only true wisdom is in knowing you know nothing.

There is only one good, knowledge, and one evil, ignorance.

The more I see, the less I know for sure.

One can have no smaller or greater mastery than mastery of oneself.

Time stays long enough for anyone who will use it.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

Art is never finished, only abandoned.

Realize that everything connects to everything else.

Why does the eye see a thing more clearly in dreams than the imagination when awake?
